Summerize column distinct

[latrous98]

I'm new to dax, and I have created a table using this code.

Summary installation =
VAR _Table = SUMMARIZECOLUMNS('produit installé'[Netbios_Name0],'produit'[FileDescription (groups)])
return DISTINCT(_Table)
but there is a problem with it as the returned table gives me a row of netbios_Name for each file description category.
is there a way to fix this .
thanks for your help

@latrous98 , if these table have join summarize should also work

SUMMARIZ('produit installé', 'produit installé'[Netbios_Name0],'produit'[FileDescription (groups)])

or

SUMMARIZ('produit', 'produit installé'[Netbios_Name0],'produit'[FileDescription (groups)])

if these does not work

Can you share sample data and sample output in table format? Or a sample pbix after removing sensitive data.

if I want to make a measure that does give the rows number and filter upon that , and then use it in a visual , what is the blueprint I need to follow ?

[latrous98]

the first table 'produit installé' (installed product ) contains all the products regardless of the groupe they belong to so doing a summerizeColumn without distinct give me rows as much as there is subproduct to a given category .
but when I applied the distinct ,I get as much rows for all the groupement even though that doesn't exist to start with
